This multi-tiered greenroof is part of a state-of-the-art LEED Platinum certified home in Philadelphia. Set on a narrow urban site, the green roofs provide the residents with spaces for cozy retreat, observing pollinators on wildflowers, and growing vegetables in a kitchen garden. Photovoltaics atop a shade pergola provide solar energy for the home, and the greenroof itself helps reduce heating and cooling energy loads and improves stormwater management on site.
